Specification of Letters Patent. Application filed September 24, 1910. Serial ROI- 583,'568.'

rammed Aug. 6, 1912.

It all-whom it may concern:

Be it known that we, CHARLES J. Pn'rniz- Sort and JOSEPH G. MOGREGOR, citizens of the United States, and residents, respectively, of Chicago, county of Cook, State of Illinois, and Oak Park, county of Cook, State oflllinois, have invented certain new and useful Improvements in Si al Lam or Lantern Glass Holders, of which the f0 lowing is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The inventlon relates to holders for glass plates, especially such as are used' in connection with signal lamps, the plate being mounted in a frame movable into and out of register withthe lens'of'the lamp.

The object of the invention is to provide simple yet effective means for removably securing the plateof glass in the frame; and it consists broadly in combining with the frame a pivoted member mounted to swing in a plane perpendicular to the face of the glass and being provided with a lifting arm or lifting the glass from its seat when the clam ing arm is raised, a spring being provide for yieldingly holding the clamping arm to the glass,' and preferably being so arranged as to hold the arm also injts retracted position.

In the accompanying drawings illustrating the invention, Figure 1 is an elevation of the signaling device detached from the lamp; Fig. 2 is an elevation of'the reverse side of one of the lass-carrying frames; Fig. 3 is a detail section on the line 3 3 of Fig.2; and Fig. 4 is a detail in perspective of the glass-retaining member.

The invention is shown as applied to a signaling device of common construction, comprising a base or casing 10 adapted to be secured to the body of a lamp or lantern, such as is used for signaling purposes on railway trains; a pair of frame-arms 11, 12, being pivotallymounted upon the casing 10 and being controlled, respectively, by means of levers 13, 14.

Each of the frame arms 10, 11, comprises an annulus 15, carried by a stem 16, the rim of the annulus being angular in form, one flange thereof constituting its diskface and affording a seat for a circular glass plate 17,

"laps the glass plate 17:

its other-flange 18 being perpendicular to its disk face-and holding'theglass against sliding-movement. A stationary'ciip-19 is attached to the outstanding-flange18of'the annulus, as by means of'solder, and over- Oppos1te the clip 19, preferably diametrically oppos te to it, the annulus 1s provided with aradially-projecting flange 20, apertured, as shownaat' 21, to receive'one-arm 22 of the movableglass-retaining clip. This,

clip, shown in perspective in Fig- 4, is formed of apiece of sheet metal folded to U shape, its arm 22 being bent inwardly slightly and recurved ad acent its extreme end'to provide a bearing surface for engaging the glass, and a lip 23 under-which a finger-nail may be can ht for raising it. The shorter arm 24 of this element engages the opposite face of the glass, projecting 1nwardly beyond the disk flan e of the annulus and aifording'means for ifting the glass from its seat w en the clamping arm 22 is raised.

The clampin member is provided with a pair of latera ly projecting lugs 25, 26, which rest against the under or inner face ,of the flange 20, and upon which bear the arms 27 28, of a bifurcated spring plate 29 a secured to the flange 20, as by means of a rivet 30. The lugs 25, 26, are located back of the aperture 21, so that the pressure of the sprin against them throws the arm 22 downwar ly against the lass, rocking it upon the rearward edge of the aperture 21. When the arm 22 is raised and tilted backward, the clamping element rocks upon-the forward edges of the lugs 25, 26, and the spring pressure upon their rearward edges holds the clamping element in its elevated position.

The described embodiment of the invention is extremely simple, effective, and chea of construction, but we do not desire to be imited to this specific form of clamping element and spring.

We claim as our invention- 1. In combination, a frame having a seat for a plate ofglass, a glass plate seated in the frame, a clamping element rockingly mounted in the frame to swing toward and away from the face of the glass, its-movement b transverse to the plane thereof, and a spring for advancing the clamping element.. j

2. In combination, a frame having a seat for .a plate 'of glass, a glass plate seated in the frame, a clampin element mounted upon the frame to roc toward and away from the face of the glass, its movement being transverse to the plane thereof, such element being provided with a lifting arm for engagin the reverse face of the glass, and a spring or advancing the clamping element.

3. In combination, a frame having a seat fora plate of glass and an aperture ad'acent the seat and a glass plate seated in the rame, a U-shaped element extending through the aperture, its arms being adapted to engage the opposite faces of a plate of glass occupying the seat, and a spring acting upon such element to yieldingly he (1 the glass to its seat.

plate seated in the frame, an arm projectmg through the aperture for bearingupon the face of the glass, and a spring acting upon the i nner end of the arm to urge its outer end toward the seat.

5. In cOmbinatiOm a-frame havin'g'a seat for a plate of glass and an aperture adjacent the seat and a glass plate seated in the.

6. In combination, a frame having aseat' for a plate of glass and anaperture adjacent the seat and a glass plate seated in the frame, a U shaped element projecting through the aperture and adapted to engage by both of its arms the opposite faces of a plate of glass when occupying the seat, such element having flat laterally projecting lugs, and a-leaf spring secured to the frame and bearing on the lugs.
